Orciprenaline(C11H17N03,211.258 g/mol) is a bronchodilatorused in the treatment of asthma.The BP assay for orciprenalinetablets is described below. Read thefollowing information carefully andanswer the questions below.(Record your answers in decimalnotation to the indicated significantfigures OR decimal places)ASSAY - 20 tablets weighing 2.597 gwere crushed to a powder. Aportion of the crushed powder(0.5456 g) was shaken with 50 mL of0.1 M HI, the mixture was filteredand made up to 100 mL. 10 mL ofthis solution was further diluted to100 mL with 0.1 M HCI. Themeasured absorbance of thediluted solution at 276 nm was0.582. Additional information: A1%72.3, stated content = 20 mg Calculate:a) The concentration oforciprenaline in the diluted solutionin mg/L b) The actual amount oforciprenaline (in mg) in the powderassayed.c) The actual amount oforciprenaline (in mg) per tablet.d) The percentage of stated contentof per tablet.
